Description One of Indonesia's most active volcanos has erupted, shooting ash and smoke nearly 1 1/2 kilometers (one mile) into the sky. State volcanology official Kristianto says Mount Soputan on central Indonesia's Sulawesi island erupted Tuesday afternoon. Kristianto, who uses one name, says there is no plan for an immediate evacuation since the nearest villages are outside the danger area of about 6.5 kilometers (4 miles) from the crater.
